PEGGlNG-MACHINE FOR PlLE FABRICS.

SPECIFICATION forming part of Letters Patent No. 479,274, dated July 19,1892. Application filed September 3, 1891. Serial No. 404.639. (Nomodel.) Patented in England February 2, 1891, No! 1,85

T0 on whom it may concern:

Be it known that we, HARVEY HEYWOOD and JOHN HOLLAND, subjects of theQueen of Great Britain, residing at Middleton, near Manchester, England,have invented a new and useful Pegging-Machine, (for which we haveobtained Letters Patent in Great Britain, No.1,854, hearing dateFebruary 2, 1891,) of which the following is a specification.

Our invention relates to what are known in the trade aspegging-niachines for pile fabrics, which are employed to effect acertain process in the finishing of pile fabrics; and the invention hasfor its object to provide continuous or nearly-continuous action of thepeg or presser-bar upon the fabric under operation, together with ahigher rate of speed in work than is at present attained.

The operation of pegging consists, chiefly, of a rapid rubbing of thepile surface of the fabric to be treated with an instrument termed inthe-trade a peg, which peg is of various designs, but is essentiallyprovided with or formed as a blade, of wood by preference, the smoothrounded edge of which, held at an angle, is dragged according to theordinary method backward and forward over the surface of the fabric inmanner somewhat similar to the motion of arazor over a strop. By thismeans the fabric, which ordinarily is caused to travel over a stationarybed-plate, has given to ita polish orfinish which greatly improves itsappearance.

We attain our objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a plan view, Fig. 2 a side elevation,and Fig. 3 a longitudinal vertical section, of a pegging-machinearranged according to one form of our invention, while Figs. 4 and 5show enlarged views, in section and elevation, of certain portions ofthe apparatus to be hereinafter described.

The same letters and figures indicate corresponding parts wherever theyoccur.

a a is the main framing of the machine, and b b the length of clothundergoing the process of pegging.

c c is the revolving roller, which is used in lieu of the ordinarystationary bed-plate, and

(l (l are pegs mounted in fixed journals (1' 6?, held by means of thesprings d d with uniformly-elastic pressure against the cloth as thesame passes over the rolling bed. These pegs are in operation placed atthe most convenient angle with the surface of the drum or roller 0 c,which in all cases is determined by experience, by preference with theirblades radial to the center thereof, and are preferably provided withapparatus, to be described, whereby they may at suitable periods betemporarily lifted out of operation to prevent any accumulation of fluffor waste or any creases or puckerings of the cloth in front of such peg.This temporary releasing of the pegs is accomplished,by preference, inthe following manner; but other equivalent means may be substituted:Upon one end of the shaft 6 e, which has motion communicated from themain gearing by worm and wheel, is fixed a dog 6, which, pressingagainst a pin or projection f upon the cam f f, causes such cam torevolve upon the eccentric bush g g. This cam presses against two bowlsh h, at tached to the levers h 713, which levers are fulcrumed at 72 andin the ordinary working position communicate pressure of the pegs cl 01upon the cloth I) I) through the links k is and short levers 10 In thecircumference of the cam ff are out at suitable intervals two or morerecesses f 2 f which recesses during revolution of the cam comeperiodically opposite thebowls h h, bypreference alternately. At suchtimes, the pressure on the bowl, and consequently on the peg, beingreleased, the peg is forced out of contact with the rolling bed 0 c, asmore clearly shown in Fig. 4, and remains out of action until therevolving cam again presents its convex surface to bear upon the bowl.In the drawings one peg, with its bowl, lever, and communications, isshown temporarily released, while the portions actuating the other pegare in the working positions.

g is a hand-leverattached to the eccentric bush, which enables both pegsto be thrown out of gear on the stoppage of the machine. This lever whenmoved over on the center 6 carries around with it the eccentric bush 9g, and consequently moves the cam ff eccentrically against the cams ofthe bowl-levers 711 711 thrusting such bowls and levers backward, thuslifting the pegs d (I out of action when required.

The cloth in its motion through the machine passes from the roll 1 underthe bar 2 and over the rod 3, where it is operated upon by the revolvingbrush Z Z, which has motion given to it by belt and pulley, as shown, orby other convenient means. Then, passing under the rod 7L and round theshaft 6 e, the cloth is carried over the bar 4, under the rod 5, roundthe roller 6 and the card-roller '7, thence over the expanding-roller 8and under the bar 9 to the revolving bed 0 c, after leaving which it iscarried under the geared shaft 10, over the card-roller 11, and sopasses under the bars 12 and 13 to a suitable roll fitted with detachingapparatus, as shown, or, it might be, to a traveling lattice or otherknown device for return to the front end of the machine. Although theseconducting-rods are shown and described, it is obvious that a number ofthem may in some cases be dispensed with or others added, according tothe amount of tension or resistance required by the cloth operated upon,and some of the rollers may have tension or drag apparatus provided, ifdesired, such as is shown attached to the card-roller 7, where abrakestrap or m passes over the pulley n n and is weighted by the lever0 0, f ulcrumed at 0', and weight 13 19, such weighting being releasedwhen necessary, on the stopping of the machine, by the depression of thelever r r, fulcru med at s and loosely connected at the other end withthe lever 0 0.

A supplementary apparatus or rollers t and u is shown in the drawingsfor the purpose of winding the fabric for transference of the same inroll form to the other end of the machine; but this forms no part ofthis our pres ent invention. Either one, two, or more pegs may be fittedto one revolving bed, or more than one revolving bed may be mounted inone machine, and other variations may be made without departing from thepeculiar character of the invention.

\Vhat we claim as our invention, and desire to secure by Letters Patent,is

1. In iiegging-niachines, the combination of apparatus for temporaryreleasement of the pegs, formed by the revolving cams f, with recessesfthe bowls h h, periodically received by such recesses, the bowl-levers7L2 h moving with the bowls, the short levers 70 70, attached to theaxis of the" pegs, and the connecting-liuks 7c is, receiving motion fromthe bowl-levers, and the hand-lever g, attached to the eccentric bush gof the cams f, whichlever when moved over on its center forces such camsf against the projecting arms on the bowl-levers h 71?, moving forwardthe same and their aforementioned connections 70 76' k 70 allsubstantially as set forth.

2. In pegging-machines, the combination of stationary pegs orresser-bars d and the revolving bed 0, over which the cloth travels,with apparatus for temporary releasement of the pegs, formed by therevolving camsf, with recesses f, the bowls h h, periodically receivedby such recesses,the bowl-levers k h moving with the bowls, the shortlevers k is, attached to the axis of the pegs, and the con necting-linksk 70', receiving motion from the bowl-levers, and the hand-lever g,attached to the eccentric bush g of the cams f, which lever when movedover on its center forces such cams f against the projecting arms on thebowl-levers 72, h moving forward the same and their aforementionedconnections 7c 70 70 k all substantially as set forth.
